The remote Windows host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - Errors exist related to microprocessors utilizing     speculative execution and L1 data cache that could     allow information disclosure. (CVE-2018-3615,     CVE-2018-3620, CVE-2018-3646)

  - A remote code execution vulnerability exists when the     Windows font library improperly handles specially     crafted embedded fonts. An attacker who successfully     exploited the vulnerability could take control of the     affected system. An attacker could then install     programs; view, change, or delete data; or create new     accounts with full user rights.  (CVE-2018-8344)

  - A remote code execution vulnerability exists in the way     the scripting engine handles objects in memory in     Microsoft browsers. The vulnerability could corrupt     memory in such a way that an attacker could execute     arbitrary code in the context of the current user. An     attacker who successfully exploited the vulnerability     could gain the same user rights as the current user.
    (CVE-2018-8385)

  - A remote code execution vulnerability exists in     Microsoft Windows that could allow remote code execution     if a .LNK file is processed. An attacker who     successfully exploited this vulnerability could gain the     same user rights as the local user.  (CVE-2018-8345,     CVE-2018-8346)

  - An information disclosure vulnerability exists when the     Windows GDI component improperly discloses the contents     of its memory. An attacker who successfully exploited     the vulnerability could obtain information to further     compromise the users system. There are multiple ways an     attacker could exploit the vulnerability, such as by     convincing a user to open a specially crafted document,     or by convincing a user to visit an untrusted webpage.
    The security update addresses the vulnerability by     correcting how the Windows GDI component handles objects     in memory. (CVE-2018-8394, CVE-2018-8396, CVE-2018-8398)

  - A remote code execution vulnerability exists in the way     that the Windows Graphics Device Interface (GDI) handles     objects in the memory. An attacker who successfully     exploited this vulnerability could take control of the     affected system. An attacker could then install     programs; view, change, or delete data; or create new     accounts with full user rights.  (CVE-2018-8397)

  - A remote code execution vulnerability exists in     'Microsoft COM for Windows' when it fails to     properly handle serialized objects. An attacker who     successfully exploited the vulnerability could use a     specially crafted file or script to perform actions. In     an email attack scenario, an attacker could exploit the     vulnerability by sending the specially crafted file to     the user and convincing the user to open the file.
    (CVE-2018-8349)

  - An elevation of privilege vulnerability exists in the     Windows Installer when the Windows Installer fails to     properly sanitize input leading to an insecure library     loading behavior. A locally authenticated attacker could     run arbitrary code with elevated system privileges. An     attacker could then install programs; view, change, or     delete data; or create new accounts with full user     rights. The security update addresses the vulnerability     by correcting the input sanitization error to preclude     unintended elevation. (CVE-2018-8339)

  - An information disclosure vulnerability exists when the     Windows kernel improperly handles objects in memory. An     attacker who successfully exploited this vulnerability     could obtain information to further compromise the users     system.  (CVE-2018-8348)

The remote Windows host is missing security update 4343899 or cumulative update 4343900. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in the way     that Microsoft browsers access objects in memory. The     vulnerability could corrupt memory in a way that could     allow an attacker to execute arbitrary code in the     context of the current user. An attacker who     successfully exploited the vulnerability could gain the     same user rights as the current user.  (CVE-2018-8403)

  - An information disclosure vulnerability exists when the     Windows kernel improperly handles objects in memory. An     attacker who successfully exploited this vulnerability     could obtain information to further compromise the users     system.  (CVE-2018-8341, CVE-2018-8348)

  - An elevation of privilege vulnerability exists in the     Network Driver Interface Specification (NDIS) when     ndis.sys fails to check the length of a buffer prior to     copying memory to it.  (CVE-2018-8342, CVE-2018-8343)

  - A remote code execution vulnerability exists when     Internet Explorer improperly validates hyperlinks before     loading executable libraries. An attacker who     successfully exploited this vulnerability could take     control of an affected system. An attacker could then     install programs; view, change, or delete data; or     create new accounts with full user rights.
    (CVE-2018-8316)

  - An information disclosure vulnerability exists when the     Windows GDI component improperly discloses the contents     of its memory.

    (CVE-2018-8355, CVE-2018-8372, CVE-2018-8385)

  - A remote code execution vulnerability exists in     Microsoft Windows that could allow remote code execution     if a .LNK file is processed. An attacker who     successfully exploited this vulnerability could gain the     same user rights as the local user.  (CVE-2018-8345,     CVE-2018-8346)

  - A remote code execution vulnerability exists in the way     that the scripting engine handles objects in memory in     Internet Explorer. The vulnerability could corrupt     memory in such a way that an attacker could execute     arbitrary code in the context of the current user. An     attacker who successfully exploited the vulnerability     could gain the same user rights as the current user.
    (CVE-2018-8353, CVE-2018-8371, CVE-2018-8373,     CVE-2018-8389)

  - A remote code execution vulnerability exists in the way     that the Windows Graphics Device Interface (GDI) handles     objects in the memory. An attacker who successfully     exploited this vulnerability could take control of the     affected system. An attacker could then install     programs; view, change, or delete data; or create new     accounts with full user rights.  (CVE-2018-8397)

  - An elevation of privilege vulnerability exists in     Windows when the Win32k component fails to properly     handle objects in memory. An attacker who successfully     exploited this vulnerability could run arbitrary code in     kernel mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts     with full user rights.  (CVE-2018-8404)

  - A remote code execution vulnerability exists in     &quot;Microsoft COM for Windows&quot; when it fails to     properly handle serialized objects. An attacker who     successfully exploited the vulnerability could use a     specially crafted file or script to perform actions. In     an email attack scenario, an attacker could exploit the     vulnerability by sending the specially crafted file to     the user and convincing the user to open the file.

The security update addresses the vulnerability     by correcting the input sanitization error to preclude     unintended elevation. (CVE-2018-8339)

  - An information disclosure vulnerability exists in     Microsoft .NET Framework that could allow an attacker to     access information in multi-tenant environments. The     vulnerability is caused when .NET Framework is used in     high-load/high-density network connections where content     from one stream can blend into another stream.
    (CVE-2018-8360)

  - An information disclosure vulnerability exists when     affected Microsoft browsers improperly allow cross-frame     interaction. An attacker who successfully exploited this     vulnerability could allow an attacker to obtain browser     frame or window state from a different domain. For an     attack to be successful, an attacker must persuade a     user to open a malicious website from a secure website.
    This update addresses the vulnerability by denying     permission to read the state of the object model, to     which frames or windows on different domains should not     have access. (CVE-2018-8351)

  - A remote code execution vulnerability exists when the     Windows font library improperly handles specially     crafted embedded fonts. An attacker who successfully     exploited the vulnerability could take control of the     affected system. An attacker could then install     programs; view, change, or delete data; or create new     accounts with full user rights.  (CVE-2018-8344)
